First success. Now with git-sources-3.3_rc6 Belkin's blue light is on, but: it fails to authenticate with the network, although it sees every wireless around... Should I unemerge (btw how?) the ndiswrapper?

You'll need to provide more info. What kind of network are you connecting to, what are you using to connect, have you tried connecting manually on the commandline and what was the output of those commands...

The router is setup as wpa2 personal - tkip . Other packages you might need are sys-apps/iproute2 net-misc/iputils sys-apps/ifplugd. Also you might have to set set rc_depend_strict="NO" in /etc/rc.conf.

dmesg's output, one thing worries me here: "renamed network interface wlan0 to wlan1" and "wlan1: link is not ready". I remember your words about "The system will remember wlan0 by MAC anyways", so do I need to recompile the kernel with Atheros (the supposedly dead card's driver)...
I think I need to "unemerge" NetworkManager at all, then.

This part shows me how to fix a problem I am having with a Logitech Unifying Device keyboard. It has nothing whaever to do with your problem.

You have a net.wlan0 symbolic link in /etc/init.d/ Its a link to net.lo

Make up your mind what you want your wireless to be called - wlan0 or wlan1. You must set up everything consistently but the name does not matter.
If you want wlan0, edit the file /etc/udev/rules.d/70-persistent-net.rules and remove the line like

and the comment above it.
Notice the part that says NAME="wlan0"This line remembers your old wlan0, and forces your new wifi to be wlan1. You should also remove the wlan1 line too, or the system will remember your new wifi as wlan1 anyway.

If you will libe with wlan1, fix the symbolic link in /etc/init.d to be net.wlan1. Delete the net.wlan0 and make a new net.wlan1
You must also remove net.wlan0 from your runlevels, if it was ever added and add net.wlan1 in its place.
Lastly keep in mind that your wifi is called wlan1 because documents will refer to it as wlan0

A little more brutal, but faster is to delete /etc/udev/rules.d/70-persistent-net.rules and reboot. udev will rewrite it for you. Be warned that if you have multiple wired interfaces, their order may change._________________Regards,

Computer users fall into two groups:-
those that do backups
those that have never had a hard drive fail.

Fellows, let me summarize this thread for future reference:
1) For f7d2102v2 net300 WiFi adapter to work one needs at least git-sources-3.3_rc6
2) Having compiled the above kernel, one emerges NetworkManager (yes, BillWho, I'll come back to your commandline way when I'm more advanced in Gentoo)
3) rm /etc/udev/rules.d/70-persistent-net
4) ln -s net.lo net.wlan0 inside /etc/init.d/
4') if one had messed up with the wlan names, the best way is to delete one:
rc-update del net.wlan1 default
5) rc-update add net.wlan0 default
6) reboot
It is salutary to issue dmesg | grep "wlan" from time to time.

After a while a resumed the fine-tuning of my Gentoo laptop.
Started by creating a wireless network at home and connecting to it.
Now, the MAC address of the router is the one that starts with CC...
The problem is: when I launch NEtworkMAnager from the very vicinity of
the router, it starts OK, but when I start from somewhere a bit further away (the dongle
still "sees" the network) and then come closer, it fails.
